This 1920 Art Deco ring is fashioned from platinum and holds a central cushion-cut pink sapphire secured by four yellow gold claws. The vibrant stone is surrounded by a structured geometric halo of sixteen old European-cut diamonds, complemented by delicate milgrain detailing and openwork gallery construction. The slender platinum shank features double fluted shoulders down the sides. Notable details visible in the piece include the textured milgrain edge along the geometric diamond mounts, the distinct four-claw setting holding the vivid pink gemstone, and the linear fluting on the ring band. At the widest point, the face measures 11.75mm across. Suitable for daily wear as an engagement or dress ring, the jewel slips onto the hand to bring period glamour to modern outfits. The piece pairs well with other fine platinum or silver-toned jewellery and can be worn independently as a statement accessory. The slim shank offers a comfortable fit for everyday use, while the low profile ensures practicality during daily activities.

FAQs

Art Deco jewellery, prominent from 1919 to 1939, is characterised by linear symmetry, bold geometric patterns, and contrasting gemstone combinations. Influenced by modern architecture and cubism, designs frequently utilised platinum mountings decorated with fine milgrain borders and diamond frames to highlight coloured central gemstones.

Art Deco rings were predominantly crafted using platinum, valued for its strength and ability to support delicate filigree and milgrain detailing. Primary central stones such as sapphires, emeralds, and rubies were typically encircled by brilliant or single-cut diamonds set in openwork geometric mounts.

Authentic Art Deco rings feature hand-applied milgrain edging, geometric platinum mountings, and hand-cut diamonds rather than modern round brilliant cuts. Genuine period pieces display clean structural symmetry, period hallmarks, and subtle signs of wear on the underside gallery and band.

Art Deco dress rings serve as a focal point when worn individually on the right hand or ring finger. Their structured architectural lines pair effectively with both contemporary tailored attire and vintage formal wear, complementing silver or white gold modern accessories.

To preserve an antique ring, clean it gently using warm water, mild soap, and a soft-bristled brush to remove dust from behind the stone settings. Store the item separately in a fabric-lined box to prevent harder gemstones from scratching the platinum or surrounding diamonds, and avoid contact with harsh cleaning chemicals.
